A size 12 hydraulic hose typically refers to the nominal inside diameter of the hose, which is 3/4 inch. Hydraulic hoses are often sized using a "dash" number system, where the number represents the hose's inside diameter in sixteenths of an inch. Therefore, a dash 12 hose (also written as -12) corresponds to 12/16 inches, or 3/4 inch.
